Win8系统的Loading效果还是很不错的，网上也有人用CSS3等技术实现，研究了一下，并打算用WPF自定义一个Loading控件实现类似的效果，并可以让用户对Loading的颗粒（Particle）背景颜色进行自定义，话不多说，直接上代码：
1、用VS2012新建一个WPF的用户控件库项目WpfControlLibraryDemo，VS自动生成如下结构：
2、删除UserControl1.xaml，并新建一个Loading的CustomControl(不是UserControl),如下图所示：
3、如果报错找不到Loading类型，请编译，下面在Generic.xaml主题文件中对Loading的样式和内容进行定义（注意添加
xmlns:system = "clr-namespace:System;assembly=mscorlib"），代码如下：
<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
